Unauthenticated server-side requests to arbitrary destinations
Published Jul 23, 2026 · Updated Jul 23, 2026
SSRF in Pepro Development Group PeproDev Ultimate Invoice 2.2.6 and earlier allows remote attackers to make server-side HTTP requests. The CNA-linked advisory does not identify the vulnerable endpoint, parameter, or request function, so the operation on untrusted input remains undisclosed. No authentication or user interaction is required; successful exploitation can contact arbitrary domains and expose information from services reachable by the WordPress host.
